Consolidation settlement
Consolidation settlement
(OP)
Hi all:
Can anybody suggest me how we consider the influence of a foundation load on soil profile. I mean if we have a footing depth at 8ft. and we have varying lean clays upto a depth of 100 ft, consolidation settlement up to which depth is significant for our calculations ?
Is it the depth where load intensity is 10% of the actual ??
Please suggest.
Thanks
NT

RE: Consolidation settlement
The nice thing about using the spreadsheet you can try various situations such as unload an area, as with a basement excavation to see it's effect on how the footing behaves. Also you can pre-load as with a surcharge and see how little footing pressures affect sub soils as a result. A tricky one is for the situation with a footing at the edge of a basement area. That may take a more elaborate way to find existing as well as added pressures down there. Sometimes we need to "estimate' between two extremes.
